The Second Brain Installer

You're re-explaining yourself to your AI every damn session — who your clients are, what you're building, the call you had Tuesday. Rebuilt from scratch, chat after chat. That's the tax that's actually chewing up your time.

This is the fix: one file you drop into your agent. It interviews you, then builds a private second brain — your business, your people, your playbooks — in about 20 minutes. Your AI finally knows your business.

Take the installer

Free. No checkout — one file and twenty minutes.

Most "second brains" are graveyards. This one compounds.

Built for the operator drowning in the doing — ops, follow-ups, admin — while the AI that's supposed to help starts every chat with amnesia.

A wiki your AI builds, then keeps.Plain Markdown, version-controlled, on your machine. Not another app — a library your agent reads and writes: your business, your people (a living CRM), your playbooks, your sources. Tailored to how you already think, in your vocabulary.

The memory bridge.Your agent's always-loaded memory file becomes a lean map that points into the wiki. Memory points; the wiki holds. Your agent stays fast, your knowledge gets deep — no context tax, no silo.

The two-move discipline.The wiki is only ever written through two moves — capture and ingest. Your AI proposes, you approve, it writes. That one rule is the whole difference between a brain that compounds and a folder that rots.

Six months in.You stop re-explaining yourself. You ask, and it answers from your world — your clients, your numbers, the decision you made in March. Nothing decided is lost; nothing learned gets learned twice.

Twenty minutes, start to finish.

01
Take it below — a paste-in prompt for Claude, one command, or the repo.The installer lives on GitHub, so you always get the current version. I run this system on my own company and keep sharpening it.
02
Boot your agent in the folder.Open Claw, Claude Code, Cursor — anything that reads a memory file — and say: Run the Second Brain installer.
03
Answer a handful of questions. Approve the shape. Walk away.It builds in the background, wires your memory file into the wiki, and teaches you the two moves on a real capture from your own conversation.

The rule that makes it stick: one win, then replicate.

Don't automate your whole operation this weekend — that's how systems die in a drawer. Install the brain, then hand it ONE thing: the follow-up you rewrite every week, the brief you keep re-explaining, the client context you rebuild every Monday.

Feel that one thing come back done. Then replicate the win — one piece at a time, until the doing works for you instead of eating you.

The installer. Three ways in.

It lives on GitHub — the living copy, updated as I sharpen it. Take the prompt, the command, or the link.

If nothing loads: the installer is a public repo — github.com/andrewsponsler/second-brain-installer

And when you want it wired deeper —

The installer is the gift. This is just an open door.

What you just took is the foundation — the same architecture I run my own operation on. The advanced layers are where it becomes a real operating edge: your calls and comms flowing in on their own, ledgers that track what everyone in your world wants, automated capture, a team of agents working the system while you live. Building that on an operator's actual business is the work I do.
